Re: [Pharo-project] Z3950 on OSX: module yaz3 not found

by HernÃ¡n Morales Durand

Hi Laurent, Thanks for the feedback, I've uploaded the repository with the missing method but I cannot reproduce the crash in Windows. Have you unmangled every function name tested? Are you running just the Z3950FFILibraryTest? Notice the Z3950FFIServerLibraryTest tests are performed against a Z39.50 server running in local host, otherwise will fail (however that shouldn't crash the VM), so you may want to run only the Z3950FFILibraryTest suite. If you or anyone want a local Zebra server for Win32 - although most configuration files should work with other platforms - for testing purposes please let me know. Does the Kant test crash the VM too? Z3950Client new server: #Acadia; query: ( Z3950Query new author: 'Kant' ). (see http://67.222.12.200:8889/WebOpus/52 for sample successful results) I will set up a Linux box tomorrow and try to reproduce there.

Ey, I want join also to the feelings of Sven and Laurent. I'm in Smalltalk from year 2000 aproximately but only in the last years I'm achieving one of my goals that is work 100% in Smalltalk in my small entrepreneurship dream called Arduino Software. A big part of this history is thanks to Pharo and Seaside and lot of other cool stuff on squeaksource. I think that the business orientation of Pharo was a key factor to caught my attention and, even when I also love Squeak and its people (a lot of us are on both sides trying to help) I have now in Pharo the tools to fight in the commercial arena. Modestly I try to help in the areas I can and in the time I have and want to say here a big big thanks to a lot of people working hard and (as Stef said) not only in the cool part of development but also on more boring (but needed stuff) as admin, doc, etc. Thank you all dear fellow of Pharo/Seaside/etc community by the effort put in this work and for the help I received each time I needed it. And also a BIG thanks to ESUG by the continuos effort to help in the Smalltalk advance. Now we must go for more in 2011, for example in develop the next big success on the startups market, this one with Pharo :) Very good 2011 to all of you!

Re: [Pharo-project] Why Smalltalk ? Which Smalltalk ?

by Jimmie Houchin

Personally I haven't read any real animosity from Levente toward Pharo in this thread. His issue was not the choice of Pharo but rather the incorrect information stated as a basis of the decision. Pharo has enough good things to represent itself without basing decisions on false data. I happen to agree with Levente about the correctness of those statements. But those were the understandings of the poster which did so without any expressed ill intent toward Squeak. People make mistakes. And to be clear as to my understanding a) removing unessential code from Squeak (Squeak, having started as a childrenâs education project, has accumulated a fair amount of cruft over the years), Squeak did not start as a children's education project. To quote the Squeak history page """ The goal was to build a system using a language as expressive and immediate as Smalltalk to pursue various application goals such as prototypical educational software, user interface experiments and another run at the Dynabook concept. """ One goal out of the three expressed was for education software, which can entail much more than children's education. The other two goals had nothing to do with education. b) clearer licensing (MIT license), Not an issue at all at the time of the post. And it is not clear that it was a real issue at the time of his decision for Pharo. In my opinion the Squeak license wasn't much of an issue for most people unless you had to answer to some corporate types. And even before Squeak became primarily MIT, it had been released under the Apache license, which a portion still remains. Squeak just happened to pursue a more challenging vetting of the source code prior to re-licensing. c) more frequent updates (think Ubuntu versus Debian), and I can see how this could be an opinion. And I see how some would disagree with it. d) being a reference implementation for the Seaside platform (perfect, exactly what I need it for). Yes, the current maintainers develop on Pharo and explicitly do not support anything else. And yes, there was a brief time that Squeak was not easily usable for Seaside. But that is no longer the case. Nor is the fact that the current maintainers using Pharo for development mean that the other ports of Seaside are any less Seaside, or less current, or less maintained. Nor does the blogger expressly state that either. Now on his blog he has edited the page to denote comments from this thread. He comments that he got these opinions from the Pharo Wikipedia entry. From that source I can see how he came to some of these conclusions. I am pro Pharo, it is what I am using to develop my business application. I am not anti Squeak. The good energy in this community needs to be based on honest truths about the benefits of Pharo. Those benefits have absolutely nothing to do with any deficiencies in Squeak. Lets keep this a pro Pharo energy, not an anti Squeak energy. A person can choose either and have made an excellent decision. There are technical differences between Squeak and Pharo. There are also vision and community differences. Plenty of real reasons to choose between them. For me, my vision and goals, Pharo is a more comfortable fit. Its a personal decision. So please, don't make me persona non grata for this post. :) And lets give Levente a break. I don't see any evil in his post. There is no wrong in seeking accurate statements. Pharo would want such from the Squeak side of things. And on to good positive energy and the fruits thereof. Jimmie

Re: [Pharo-project] Z3950 on OSX: module yaz3 not found

by laurent laffont

Hi Hernan, finally I switch back to Linux to make it work, OSX gives me headaches. So on linux the yaz module is found. I get the "Unable to find function address" but I found that writing: <cdecl: ZOOMOptions 'ZOOM_options_create' (void) module: 'yaz'> instead of <cdecl: ZOOMOptions '_ZOOM_options_create@0' (void) module: 'yaz3'> works. If I understand, function names are not mangled when compiling with gcc on Linux. Trying to run tests I've also had a "could not coerce arguments" in Z3950FFILibrary>>createConnectionTo:port because Z3950TestCase>>portNumber answers a String and <cdecl: ZOOMConnection 'ZOOM_connection_new' (char* short) module: 'yaz'> so it's waiting for a short. I've replaced portNumber to answer a SmallInteger. And now the image crashes on connectionIsIdle call: write(1, "\ncreateConnectionTo:port:", 25) = 25 write(1, "\nconnectionIsIdle:", 18) = 18 rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 write(1, "\n", 1) = 1 tgkill(25830, 25830, SIGABRT) = 0 --- SIGABRT (Aborted) @ 0 (0) --- Any idea ?

Re: [Pharo-project] How I can do SWF files playing in pharo?

by StÃ©phane Ducasse

Hi denis Long time again we could play flash 3.0 in squeak but this was at a time where the flash license was forbidding even the writing of program interpreting flash internal data. So the flash package did not get maintained to support flash 40 and after it got obsolete. After the license changed and it is possible to get a flash importer/ interpreter. Now everything I said can be false because it was long time ago. Now it would be cool to have a flash player around :) Stef > Hello > > I search way for playing swf files in morphic. > > Can you advise some approaches for implementing this stuff? > > I found flash package in squeaksource. But It support only swf format version 3. Its realy up to day. I cant read required flash files. And I dont know how I can improve current implementation for recent swf format. Maybe I wrong but I hear swf format have no open specification. > > I found gstreamer flash plugin. And there is gstreamer binding in squeaksource. Is somebody try playing flash by gstreamer? And is this will be different then playing video? > > > Best regards, > Denis > >
